Figure 4From: Exploiting Nonlinear Recurrence and Fractal Scaling Properties for Voice Disorder Detection RPDE analysis results. Results of RPDE analysis carried out on the two example speech signals from the Kay database as shown in figure 1. (a) Normal voice (JMC1NAL), (b) disordered voice (JXS01AN). The values of the recurrence analysis parameters were the same as those in the analysis of figure 3. The normalised RPDE value H normis larger for the disordered voice.Back to article page
